Hi! I'm not sure how you specify "confirmed to be different", but otherwise this query might do: http://tinyurl.com/jjpnhuo It shows each pair twice (because I'm lazy :) and I have no idea if they are same person of different - short of explicit usage of P1889 which almost never happens I don't think there's a good generic way. One pair that seems to be different is: https://www.wikidata.org/wiki/Q644401 https://www.wikidata.org/wiki/Q510034 but short of manual examination I see no way to know one way or another. -- Stas Malyshev smalyshev(a)wikimedia.org

But there certainly are some confirmed twins in there with quite similar names. There are also some queries narrowed to particular first names or particular professions at https://www.wikidata.org/wiki/Wikidata:WikiProject_Data_cleaning/matched_bi… That page hasn't been updated since the SPARQL service was very very new, so the counts are now all probably way off. One early case I remember was a sportsman that we had separate articles on as a cricketer and as a footballer, until his career was cut short by World War I. But I think he has now been merged on en-wiki. I see we also currently have https://en.wikipedia.org/wiki/Jack_Jenkins_(rugby_player) https://en.wikipedia.org/wiki/John_Jenkins_(rugby_league) -- though the dates on the latter have been questioned. Hope this helps, James.
